2016-11-11ocfs2: fix not enough credit panicJunxiao Bi
The following panic was caught when run ocfs2 disconfig single test (block size 512 and cluster size 8192). ocfs2_journal_dirty() return -ENOSPC, that means credits were used up. The total credit should include 3 times of "num_dx_leaves" from ocfs2_dx_dir_rebalance(), because 2 times will be consumed in ocfs2_dx_dir_transfer_leaf() and 1 time will be consumed in ocfs2_dx_dir_new_cluster() -> __ocfs2_dx_dir_new_cluster() -> ocfs2_dx_dir_format_cluster(). But only two times is included in ocfs2_dx_dir_rebalance_credits(), fix it. This can cause read-only fs(v4.1+) or panic for mainline linux depending on mount option. ------------[ cut here ]------------ kernel BUG at fs/ocfs2/journal.c:775! invalid opcode: 0000 [#1] SMP Modules linked in: ocfs2 nfsd lockd grace nfs_acl auth_rpcgss sunrpc autofs4 ocfs2_dlmfs ocfs2_stack_o2cb ocfs2_dlm ocfs2_nodemanager ocfs2_stackglue configfs sd_mod sg ip6t_REJECT nf_reject_ipv6 nf_conntrack_ipv6 nf_defrag_ipv6 xt_state nf_conntrack ip6table_filter ip6_tables be2iscsi iscsi_boot_sysfs bnx2i cnic uio cxgb4i cxgb4 cxgb3i libcxgbi cxgb3 mdio ib_iser rdma_cm ib_cm iw_cm ib_sa ib_mad ib_core ib_addr ipv6 iscsi_tcp libiscsi_tcp libiscsi scsi_transport_iscsi ppdev xen_kbdfront xen_netfront fb_sys_fops sysimgblt sysfillrect syscopyarea parport_pc parport acpi_cpufreq i2c_piix4 i2c_core pcspkr ext4 jbd2 mbcache xen_blkfront floppy pata_acpi ata_generic ata_piix dm_mirror dm_region_hash dm_log dm_mod CPU: 2 PID: 10601 Comm: dd Not tainted 4.1.12-71.el6uek.bug24939243.x86_64 #2 Hardware name: Xen HVM domU, BIOS 4.4.4OVM 02/11/2016 task: ffff8800b6de6200 ti: ffff8800a7d48000 task.ti: ffff8800a7d48000 RIP: ocfs2_journal_dirty+0xa7/0xb0 [ocfs2] RSP: 0018:ffff8800a7d4b6d8 EFLAGS: 00010286 RAX: 00000000ffffffe4 RBX: 00000000814d0a9c RCX: 00000000000004f9 RDX: ffffffffa008e990 RSI: ffffffffa008f1ee RDI: ffff8800622b6460 RBP: ffff8800a7d4b6f8 R08: ffffffffa008f288 R09: ffff8800622b6460 R10: 0000000000000000 R11: 0000000000000282 R12: 0000000002c8421e R13: ffff88006d0cad00 R14: ffff880092beef60 R15: 0000000000000070 FS: 00007f9b83e92700(0000) GS:ffff8800be880000(0000) knlGS:0000000000000000 CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033 CR2: 00007fb2c0d1a000 CR3: 0000000008f80000 CR4: 00000000000406e0 Call Trace: ocfs2_dx_dir_transfer_leaf+0x159/0x1a0 [ocfs2] ocfs2_dx_dir_rebalance+0xd9b/0xea0 [ocfs2] ocfs2_find_dir_space_dx+0xd3/0x300 [ocfs2] ocfs2_prepare_dx_dir_for_insert+0x219/0x450 [ocfs2] ocfs2_prepare_dir_for_insert+0x1d6/0x580 [ocfs2] ocfs2_mknod+0x5a2/0x1400 [ocfs2] ocfs2_create+0x73/0x180 [ocfs2] vfs_create+0xd8/0x100 lookup_open+0x185/0x1c0 do_last+0x36d/0x780 path_openat+0x92/0x470 do_filp_open+0x4a/0xa0 do_sys_open+0x11a/0x230 SyS_open+0x1e/0x20 system_call_fastpath+0x12/0x71 Code: 1d 3f 29 09 00 48 85 db 74 1f 48 8b 03 0f 1f 80 00 00 00 00 48 8b 7b 08 48 83 c3 10 4c 89 e6 ff d0 48 8b 03 48 85 c0 75 eb eb 90 <0f> 0b eb fe 0f 1f 44 00 00 55 48 89 e5 41 57 41 56 41 55 41 54 RIP ocfs2_journal_dirty+0xa7/0xb0 [ocfs2] ---[ end trace 91ac5312a6ee1288 ]--- Kernel panic - not syncing: Fatal exception Kernel Offset: disabled Link: http://lkml.kernel.org/r/1478248135-31963-1-git-send-email-junxiao.bi@oracle.com Signed-off-by: Junxiao Bi <junxiao.bi@oracle.com> Cc: Mark Fasheh <mfasheh@versity.com> Cc: Joel Becker <jlbec@evilplan.org> Cc: Joseph Qi <joseph.qi@huawei.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
2016-11-11Revert "console: don't prefer first registered if DT specifies stdout-path"Hans de Goede
This reverts commit 05fd007e4629 ("console: don't prefer first registered if DT specifies stdout-path"). The reverted commit changes existing behavior on which many ARM boards rely. Many ARM small-board-computers, like e.g. the Raspberry Pi have both a video output and a serial console. Depending on whether the user is using the device as a more regular computer; or as a headless device we need to have the console on either one or the other. Many users rely on the kernel behavior of the console being present on both outputs, before the reverted commit the console setup with no console= kernel arguments on an ARM board which sets stdout-path in dt would look like this: [root@localhost ~]# cat /proc/consoles ttyS0 -W- (EC p a) 4:64 tty0 -WU (E p ) 4:1 Where as after the reverted commit, it looks like this: [root@localhost ~]# cat /proc/consoles ttyS0 -W- (EC p a) 4:64 This commit reverts commit 05fd007e4629 ("console: don't prefer first registered if DT specifies stdout-path") restoring the original behavior.

2016-11-11swapfile: fix memory corruption via malformed swapfileJann Horn
When root activates a swap partition whose header has the wrong endianness, nr_badpages elements of badpages are swabbed before nr_badpages has been checked, leading to a buffer overrun of up to 8GB. This normally is not a security issue because it can only be exploited by root (more specifically, a process with CAP_SYS_ADMIN or the ability to modify a swap file/partition), and such a process can already e.g. modify swapped-out memory of any other userspace process on the system.

2016-11-11mm/cma.c: check the max limit for cma allocationShiraz Hashim
CMA allocation request size is represented by size_t that gets truncated when same is passed as int to bitmap_find_next_zero_area_off. We observe that during fuzz testing when cma allocation request is too high, bitmap_find_next_zero_area_off still returns success due to the truncation. This leads to kernel crash, as subsequent code assumes that requested memory is available. Fail cma allocation in case the request breaches the corresponding cma region size.

2016-11-11shmem: fix pageflags after swapping DMA32 objectHugh Dickins
If shmem_alloc_page() does not set PageLocked and PageSwapBacked, then shmem_replace_page() needs to do so for itself. Without this, it puts newpage on the wrong lru, re-unlocks the unlocked newpage, and system descends into "Bad page" reports and freeze; or if CONFIG_DEBUG_VM=y, it hits an earlier VM_BUG_ON_PAGE(!PageLocked), depending on config. But shmem_replace_page() is not a common path: it's only called when swapin (or swapoff) finds the page was already read into an unsuitable zone: usually all zones are suitable, but gem objects for a few drm devices (gma500, omapdrm, crestline, broadwater) require zone DMA32 if there's more than 4GB of ram.

2016-11-11mm, frontswap: make sure allocated frontswap map is assignedVlastimil Babka
Christian Borntraeger reports: With commit 8ea1d2a1985a ("mm, frontswap: convert frontswap_enabled to static key") kmemleak complains about a memory leak in swapon unreferenced object 0x3e09ba56000 (size 32112640): comm "swapon", pid 7852, jiffies 4294968787 (age 1490.770s) hex dump (first 32 bytes): 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 ................ 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 ................ backtrace: __vmalloc_node_range+0x194/0x2d8 vzalloc+0x58/0x68 SyS_swapon+0xd60/0x12f8 system_call+0xd6/0x270 Turns out kmemleak is right. We now allocate the frontswap map depending on the kernel config (and no longer on the enablement) swapfile.c: [...] if (IS_ENABLED(CONFIG_FRONTSWAP)) frontswap_map = vzalloc(BITS_TO_LONGS(maxpages) * sizeof(long)); but later on this is passed along --> enable_swap_info(p, prio, swap_map, cluster_info, frontswap_map); and ignored if frontswap is disabled --> frontswap_init(p->type, frontswap_map); static inline void frontswap_init(unsigned type, unsigned long *map) { if (frontswap_enabled()) __frontswap_init(type, map); } Thing is, that frontswap map is never freed. The leakage is relatively not that bad, because swapon is an infrequent and privileged operation. However, if the first frontswap backend is registered after a swap type has been already enabled, it will WARN_ON in frontswap_register_ops() and frontswap will not be available for the swap type. Fix this by making sure the map is assigned by frontswap_init() as long as CONFIG_FRONTSWAP is enabled.

2016-11-11drm/amdgpu: Attach exclusive fence to prime exported bo's. (v5)Mario Kleiner
External clients which import our bo's wait only for exclusive dmabuf-fences, not on shared ones, ditto for bo's which we import from external providers and write to. Therefore attach exclusive fences on prime shared buffers if our exported buffer gets imported by an external client, or if we import a buffer from an external exporter. See discussion in thread: https://lists.freedesktop.org/archives/dri-devel/2016-October/122370.html Prime export tested on Intel iGPU + AMD Tonga dGPU as DRI3/Present Prime render offload, and with the Tonga standalone as primary gpu. v2: Add a wait for all shared fences before prime export, as suggested by Christian Koenig. v3: - Mark buffer prime_exported in amdgpu_gem_prime_pin, so we only use the exclusive fence when exporting a bo to external clients like a separate iGPU, but not when exporting/importing from/to ourselves as part of regular DRI3 fd passing. - Propagate failure of reservation_object_wait_rcu back to caller. v4: - Switch to a prime_shared_count counter instead of a flag, which gets in/decremented on prime_pin/unpin, so we can switch back to shared fences if all clients detach from our exported bo. - Also switch to exclusive fence for prime imported bo's. v5: - Drop lret, instead use int ret -> long ret, as proposed by Christian.
